chloe had a homework assignment that she was working on. she wanted to do well on it, so she was trying to remember her strategy for solving equations with variables on both sides of the equal sign. what would you tell her is the best strategy?
a) just add everything together, you don't need to pay attention to the variables. you got this, girl!
b) isolate the variable by using inverse operations, and then look for any parenthesis where you will need to use the distributive property.
c) go backwards in pemordaors, combine like terms, then use the distributive property.
d) look for parenthesis and apply the distributive property; combine like terms; move your variable terms to one side and constants to the other side of the equal sign; go in reverse pemordaors to isolate the variable using inverse operations.
